An npn BJT has emitter, base, and collector doping levels of 1019 cm????3, 5 1018 cm????3, and 1017 cm????3, respectively. It is

biased in the normal active mode, with an emitter-base voltage of 1V. If the neutral base width is 100 nm, the emitter is 200 nm wide, and we have negligible base recombination, calculate the emitter current, emitter injection efficiency, and base transport factor

Components:

1.Inlet tube

2. Wheel

3. Exhaust

4. Engine

5.Air tank

6.Pressure gauge

7.Stand

8. Gate valve

b)

The efficiency of air engine is less as compare to efficiency of electric engine and this is not ecofriendly because it produce green house gases.These gases affect the environment.

c)

it can run around 722 km when it is full charge.
